[MMD] Bone tail!

Long time no see, gumroad...

Today I bring you a bone tail that took me 3 hours and 6 references. I adore it.

This is copy+pasted from the readme:

KNOWN ISSUES:
On physics v1 the very last bone stretches kind of weird with very quick spins.
Fortunately it looks kind of like a smear frame and it's not that noticeable anyway.

OTHER STUFF:
Bone tail modelled in Metaseq4, textured in CSP+PSI2, rigged in PMXE by WOLFENMALLOWS

To connect it to your model, select the "TAIL_BASE" bone and change its parent to the "LOWER BODY BONE" or the "WAIST BONE", depending on preference. The tail physics are connected to themselves and will not require connection to the body.
